'PLANING ATTACHMENT FOR LATHES.

SPECIFICATION formingpart of Letters Patent No. 275,693, dated April 10, 1883.

Application filed August 28, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, MILES G. NIXON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Attachment to Foot and Power Lathes for Planing Metal, which attachment, with a lathe, forms a combined lathe and planer, of which the following is a specification.

The object of the present invention is to provide a combined lathe and planerthat is to say, a single apparatus or, mechanical tool that may be used either as a lathe or as a planer, as may be desired and the present invention consists in combining with the ordinary horizontal lathe bed or table a vertical planer-bed,

and providing the apparatus with a compound slide-rest adapted to hold and adjust not only the lathe-tools, but also the planer-tools, the planer and lathe both having the same operating mechanism. The planer bed or frame is secured to the main frame of the machine in a vertical position, and to one side of the revolvin g lathe, so as not to interfere with its operation or the work revolving therein. The compound slide-rest isprovided with a box removably secured to its transverse slide, on which box the planer-tools are mounted in suit able holders.- The main or longitudinal leading-screw of the compound slide-rest is provided with a ratchet-wheel, and operated by a pawl connected with the driving mechanism, whereby the feed of the planer may be eifected automatically. By this means I am' enabled to produce a combined lathe and planer at a cost little in excess of that of the ordinary single instrument, whether lathe or planer, and thus save to many machinists, who have occasional use for both lathe and planer, practi-' cally the cost of one of said machines; and my combined lathe and planer is so constructed that it may be readily fitted up from any ordipound slide-rest enlarged. Figs. 5 and 6 are end and top views of the same, respectively. Figs. 7, 8, and 9 are similar views of a modification, showing the application of my invention to an ordinary foot-lathe slide-rest havin g short leading-screw in the slide-rest itself.

A is the planer bed or frame, securely bolted to the leg of the lathe at A, and by means of the brackets B B to the lathe-bed at B B.

'(J is the table of the planer, reciprocating vertically in the slides D D by means of the bent connecting-rod E, which isjointed to table 0 at Z.

F is the planer-crank.

H and G are respectively the driving and driven wheels to reduce the speed.

1 is a double bent eccentric-rod, receiving its motion from crank F near its large eye. The other end ofeccentric-rod I is apawl, and works ratchet-wheel K, which, by turning the leading-screw L, to which it is keyed, accomplishes the horizontal feeding by means of a nut situated in slide-rest N. The transverse feeding is performed by the small crank M, belonging to the lathe slide-rest.

N is the compound slide-rest.

Q is whatl term the box. It is bolted to the transverse sliding part P of the slide-rest at P P, and is made to slide across the latheslides at Y Y, and is further secured by slidin g on the under part, 0, of the slide-rest, which has to be fitted to receive it. The leadingscrew works in the female thread at Rthe lower part of 0. The part S of the tool-holder is bolted securely to box Q by means of bolt S. Part T is the tool-holder proper. It is hinged to part S, so as to flop up when the table 0 is returning.

The tool is shown atX, Figs. 2 and 3. It is secured by bolt U. Figs. 4, 5, and 6.

When it is desirable to use the lathe as a lathe, the small gear-wheel H is removed, the bolts P P are taken out, and the box, with its appendages, is slid off. The rest of the planing attachment is allowed to stand, as it will not interfere with the full operation of the lathe.

Figs. 7, 8, and 9 show a modification of the compound slide-rest as fitted up for a planer from an ordinary foot-lathe slide-rest. The construction is similar to that just described, excepting that the box Q is cut out or arched ICC at W, to allow the long slide V to project either side beyond it. When titted to a slide-rest of this character it will be entirely hand-feeding.

I am aware that prior to my invention plan- 5 in g attachments to lathes have been made, and therefore I do not claim such attachments, broadly; but

\Vhat I do claim as my invention, and desire to secure by Letters Patent, isto 1. The combination, with the shears, crankshaft, and leading-screw of a turninglathe, of the planer-bed attached to said shears, the planer-table, mechanism for reciprocating said table, and a pawl and ratchet-wheel for operat- 15 ing the feed-screw, substantially as described.

2. The combination, with the shears, leading-screw, and shaft of a turning-lathe, of the interchangeable lathe and planer tool holding devices, substantially as described.

3. Thecombinatiomwith the vertical planer- 20 bed and planer'table reciprocating therein, of the interchangeable lathe and planer tool holding devices, and the shears for supporting said tool-holding devices, to which the planer-table is attached, substantially as specified.
